Get the text body content of a MIME part.

Explains and demonstrates the GetBodyEncoded and GetBodyDecoded methods. This example uses the MIME test data located at http://www.chilkatsoft.com/testData/sampleMime1.txt

The sampleMime1.txt contains:

Content-Type: multipart/mixed;
 boundary="------------070404010201060604000708"

This is a multi-part message in MIME format.

Content-Type: text/plain; charset="utf-8"

    //  The sampleMime1.txt is a MIME document with a top-level
    //  multipart/mixed containing 3 sub-parts, each of which has the
    //  same body text but with different content-transfer-encodings and
    //  using different character encodings (utf-8 and iso-8859-1).

    //  Calling mime.GetBodyEncoded or mime.GetBodyDecoded on the
    //  top-level multipart/mixed MIME object will return an empty string.
    //  It is because the "body" of a multipart MIME object is always empty.
    //  A multipart MIME object contains sub-parts (each a MIME object),
    //  and it is only the leaf-objects that can have non-empty bodies.

    //  Get GetBodyDecoded method returns the body text decoded
    //  from whatever the content-transfer-encoding may be, and
    //  converted from whatever charset encoding might be used.
    //  In this case, calling GetBodyDecoded on each of the three
    //  sub-parts will return the same string.
    //  To demonstrate:
    CkMime part1;
    part1 = mime.GetPart(0);

    //  The GetBodyEncoded method will NOT decode from
    //  whatever content-transfer-encoding is used.  However, it will
    //  convert from whatever internal character encoding
    //  may be used to return a string appropriate for the calling
    //  programming language (for example, in .NET or any language
    //  using ActiveX, all strings are Unicode..)
